To a/ZZ whom it may concern.-

Be it known that I, RICHARD WEGNER, of Neu-Britz, near Rixdort', in the Kingdom of Prussia and German Empire, have invented a new and useful Machine for Raising YLiquids, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to an improved liquid-raising apparatus or siphon which is devised on the principle that the variations of the volume of air confined in a closed vessel or chamber which are brought about by combustion, are capable of being utilized direct for raising liquids, that is to say, without the assistance of a plunger or pump, or the like. One form of apparatus by which this principle may be carried into practice is illustrated in the accompanying drawings, in which- Figure l is a central vertical section of an apparatus constructed according to this invention. Fig. 2 is a plan of the same; and Figx is a side elevation, partly in vertical section, of a modified form of apparatus adapted for raising liquids lto comparatively great heights.

In a large vessel a is arranged a frame or support h which is adapted to support a lamp and at the same time to hold and guide the inner mechanism, that is to say, the two iioats t' and 7c. The top of the vessel is in the form of a lid or cover o hinged or pivoted atf and provided with an adjustable balance weight g, the said cover being adapted to be temporarily opened for the admission of fresh air. Connected with the bottom of the cylinder is a suction pipe d, which, like ordinary pumps, is fitted with a foot valve and strainer. The

lower end of this pipe descends into the liq,

uid to be raised, while another pipe e, also provided with a valve Whichaft'ords the liquid a passage to the exterior, serves to discharge the elevated liquid. In the hinged lid c, is provided a small air-valve h, in such a manner that, by opening it, the inner and outer pressures may be equalized.

ln the lower part or space ot' the vessel are arranged two floats t' and k capable of movement in the verticaldirection, the float k,being adapted to release or withdraw a small spring bolt l, by means of a cord k2 passing round a roller 7c', which bolt is normally pressed from right to left by a spring l. The loat t', is moved up and down by a straight rod t" which is provided with a conical collar i2 to enable the said rod and float to be secured in their highest position by means of the spring bolt Z, their downward stroke being limited by the length of a cord or chain n, by means of which the upper end of the float-rod 1l is suspended from the lid c and which is adapted to close this lid automatically as soon as the iioat sinks by its own weight. When, however, the oat t' is raised by the rising fluid, the upper end of the Heat-rod t" strikes the small lever h and thereby opens the air-valve h, when equalization of pressure or tension takes place. f

The operation of the apparatus is as follows: The lamp arranged within the vessel a rst .burns while the lid c is closed. As soon as the greater part of the oxygen contained in the airis consumed by lthe llame, the ame decreases in size, while at the same time the diminution of the oxygen causes a gradual rarefaction of the air, owing to which the liquid rises in the elevating tube or siphon, the sucking action being moreover enhanced by the fact that, as the air becomes heated by the flame, a portion of the air is expelled, thereby assisting the creation of a vacuum. As the water rises the loatt' is lifted, and the rod t" secured thereto consequently impinges against the lid c, which however, for the time being remains closed owingto external pressure, it only opening when the valve h opens and mutual compensation takes places between the external and internal pressures. The lid then springs open to the extent to which it is permitted to do so by the cord or chain n attachedto the Boat-rod, and the water issues from the vessel through the pipe e. The float t' is now retained in its highest position by the bolt Z until the said bolt is released by the auxiliary tloat lc, as it sinks together with the liquid. The iloat then drops, and, carrying with it the lid c, through the medium of the cord n causes the said lid to close by its own weight. While the lid o was open, a fresh supply of air was admitted into thevessel, with the result that the flame resumed its normal size; so that when the lid is closed,

IOO

the arrangement operates as before. The liquid is in this manner intermittently raised.

Fig. 3 represents a complete liquid raising plant arranged to elevate liquid to comparatively great heights and to deliver it onto the several floors or stories of a building or the like by means of the siphon above described. a designates the vacuum chamber which is constructed as shown in Fig. 1. This cha1nber or vessel in the present arrangement is situated at the highest point or limit and from it branch off the pipes leading down to the several floors or stories. The suction pipe 2 communicates with a vessel 3, closed on all sides and arranged on the level to which the liquid must `be raised for the first or lowermost Hoor. This vessel is provided with a iioat which acts upon the lever 6 in the manner illustrated in the drawings, and which through the medium of a chain 7, tirst slightly lifts the air-valve h from its seat, and then opens the lid c. The suctioirpipe d, extending into the well, is provided at its lower part as in the first arrangement with a footvalve and a strainer (see Fig. 1) and has a sufticiently wide diameter to suit the requirements; while the pipe 2, already mentioned, may be of smaller diameter.

When suction commences in the vessel a, in the manner described with reference to Fig. l, a vacuum is created in the pipes 2 and d and the receptacle 3 and the water rises and iills the vesselor receptacle 3, while the valve 10 in the said receptacle 3 is closed by the external upwardly acting pressure of the air. As the water-level rises, the oat is lifted and through the float 5, lever 6, chain '7 and valve h, the opening of the lid c is eected with the result that air is admitted into the chamber 3, so that the valve 10 opens, and the water rushes into another reservoir 11, which is open at the top. When suction recommences, the same operations are repeated, while at the same time the float 14 having opened the valve 15, the pipes 12 and 13 draw in liquid and convey it into the reservoir 16, from which, as before explained, it may be farther raised as far as the next story. When the water reaches the uppermost vessel a, the floats 2' and 7c operate in the manner described with reference to Fig. 1. As long as there is no water in the vessel a, the weight of the iloat k draws back the bolt Z so that it will allow the rod il to return to its normal position, and the weight of the oat t' will close the lid c when the oat 5 is raised by the water entering the vessel 3.

It will readily be understood that the satisfactory continuance or repetition of the operations above described is not limited to any number of oors or stories.

NVhat I claim, and desire to secure by Letters Patent of the United States, is
